[0002] Corrugated guardrails are protective facilities used in places such as highways, railways, and airports. Their main function is to ensure driving safety. Corrugated guardrails are usually used to control the direction of vehicle travel, prevent vehicles from deviating from the normal road or running off the road, and prevent accidents from happening.

[0003] Depending on the highway grade, the specifications of corrugated guardrails also vary. In order to meet the protective effect of corrugated guardrails, the horizontal height of corrugated guardrails is usually set between 0.5 meters and 1.2 meters. The specific height needs to be adjusted according to the actual situation.
